JOHN F. WERDER, OF LAKEWOOD, OHIO DISCHARGE NOZZLE Application filed March 9,

This invention relates to the art of discharge nozzles for metal containers and is adapted especially for use in connection with containers of lubricants.

Although capable of general utility in the pouring or-discharge of liquids from a container, yet the present invention is especially advantageous when used in connection with lubricants which are stored in metal con- 10 tainers under substantial internal pressure so that they may be discharged therefrom under their own pressure. Experience has shown, however, that in the packaging and dispensing of gas-charged lubricants from their containers, difiiculty has been caused by the leaking of the same from the container through the nozzle with the result that some of the lubricant itself is lost and furthermore, the purpose of the internalpressure is defeated.

The purpose of the present invention therefore consists in the provision of a discharge nozzle with a closure therefor whichmay be sealed so effectively as to prevent escape of the gas-charged lubricant therefrom and which may be sealed in such effective manner without the employment of gaskets or other additional sealing means.

Other objects will appear from the follow-' ing description and claims when considered to ether with the accompanying drawing.

ig. 1 is a partial View in elevation illustrating the application of the present form of discharg'emozzle to a cylindrical form of metal container; Fig. 2 is a vertical sectional view through the discharge nozzle; Fig. 3

is a plan view thereof taken on line 3-3 of Fig. 2; and Fig. 4 is a vertical sectional view of a modified form of nozzle.

It is to be understood that the present disclosure is merely for purposes of illustration and that the same construction of nozzle may be applied also to other forms of containers or to discharge outlets and that there may 5 a so be effected modifications or variations in the construction of the present form of nozzle as herein set forth and claimed.

In the one embodiment of invention illustrated in Fig. 1, the nozzle is placed on top of a cylindrical container and at a point near 1931. Serial N0. 521,230.

the edge thereof so that it may be employed for pouring the lubricant from the container upon tilting the same. This nozzle may be attached to the head of the container in any suitable manner.

The nozzle itself comprises the tubular neck or spout member 1 which is connected directly to the head 2 of the container, the body of which is indicated in a general way by reference numeral 3. The upper end portion of the neck 1 is screw--threaded, as indicated at 4, for engagement by corresponding threads upon the inside of the annular depending flange 5 of the closure member. The top portion 6 of the closure member is provided with the pouring openings 7 which may be of any size and number. If so desired, a single opening 7 may be provided. In the present illustration, the openings 7 are spaced about the top of the closure and are located just within the "flange 5 so as to have communication with the passage 1 when the closure member is in open position. I The central portion of the closure member is recessed upon its inner surface, as indicated at 6*, so as to provide an annular edge 8 of right angle form for engagement with the tapered or conical surface 9 upon the outside end portion of the neck member 1. Both the closure and neck members are formed of semi-soft metal and the parts are so constructed and arranged that upon screwing the closure member to fully closed position,

the right angle annular edge part of the closure memberwill have line contact with the conical surface 9 for effective seating and sealing engagement therewith. These parts are so constructed that when the closure member is in such sealing engagement, the reduced central portion of the closure member is still free of engagement with the upper end of the neck member 1.

As will be seen from Fig. 2, the pouring openings 7 extend through the top of the closure member at points between the annular edge 8 and the inner surface of the annular flange 5 so as to open at their inner ends for communication with the space between the conical surface 9 of the neck memployed, and also the line contact between these parts. According to the present invention, itis possible to form only one of the members, that is, either the neck member 1 or the closure member of semi-soft material or, as above stated, both of these members may be formed of such material. As a result, the gas-charged lubricant may be maintained within the container against danger of escape, by merely screwing down the closure member in the manner explained and without the employment of any additional sealing means. In order to dispense any desired quantityof the gas-charged lubricant of the container, it is merely necessary to unscrew the closure member and tilt the container, whereupon the lubricant will find its way through the circuitous passage referred to .and out through the discharge opening 7.

The present form of nozzle and closure is of a comparatively simple construction which may be manufactured and sold at comparatively low cost and at the same time, the nozzle and closure are of such construction that they will serve as an effective sealing means and also as an effective means of discharge without the employment of other parts than those herein disclosed.

As a modification, the closure herein .disclosed may be constructed without-any apertures therethrough, in which case it Would serve merely as .a dependable closure which is capable of being manufactured at a comparatively low cost and can be easily and quickly applied to and removed from the nozzle.

In the modified form of nozzle illustrated in Fig. 4, the container 10 which may be of any form, has attached thereto at its discharge opening the neck 11 which receives the plug closure member 12 by screw-thread engagement. The inner end of the member 12 is closed and of conical form, as at 13, for line contactv with the edge of the annular shoulder 14 provided within the neck member 11. The inner end of the plug member 12 is provided with the transverse ports 15 which afi'ord communication between the chamber or space within the neck member 11 and the discharge outlet 16 which extends axially thereof.

The extreme inner end of the closure plug 12 does not en age the bottom of the chamber in the neck member 11 but is spaced at this point from the neck member when the plug member 12 is in fully closed position. And either one or both of the members 11 and 12 are formed of semi-soft metal so as to ensure an effective seating engagement between the surface 13 on the edge 14 when the plug is screwed into closed position. The rotation of the plug uponthe shoulder 14 will cause a deformation in the metal and the formation of a sealing engagement between these members. The plug member 12 has the flange 12 to facilitate turning of the same.

According to the present form of illustration, there are provided four parts 15 arranged ninety (90) degrees apart, but any number may be provided, one or more, and this particular form of device maybe modified in other Ways also. In fact, by omission of the ports 15 altogether, this form of device is adaptable for use as an eflicient form of sealing closure, as above explained in connection with the form of device illustrated in Fig. 2.

As above stated, the invention herein set forth, is capable of various adaptations and modifications, all of which are to be understood as being comprehended by the following claims.
